这在技术上影响Rack,而不是Rails,我猜这是一个bug。。。Rack似乎无法正确解析嵌套查询。。。
should "parse nested query strings correctly" do
Rack::Utils.parse_nested_query("foo").
should.equal "foo" => nil

should.equal "foo" => ""

message.should.equal "expected Hash (got String) for param `y'"
lambda { Rack::Utils.parse_nested_query("x[y]=1&x[]=1") }.

message.should.match(/expected Array \(got [^)]*\) for param `x'/)

should.raise(TypeError).
message.should.equal "expected Array (got String) for param `y'"
end
另一方面,我怀疑查询应该更正确地写为:
http://example.com/?b[]=1&b[a]=2
或
http://example.com/?b[a]=1&b[a]=2
